Why not sue the Wright brothers estate for inventing the whole business??? Or Charles Lindbergh for starting Atlantic crossings, the CO DC10 was going to cross wasn't it? So surely old Chuck could be discredited?
How about just suing the people that designed Concorde for their omissions and lack of testing in this area or instructors that didn't cover this scenario in the simulator?
Come on... French justice system muct be idling or someone is looking to move to the politics and is trying to make a name and get the old face on screen.
